将两思路和二为一

（1）股价跌破布林下轨，参数设为20.2
（2）源码：VAR2:=(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))*100;
VAR3:=SMA(VAR2,5,1);
VAR4:=SMA(VAR3,3,1);
VAR5:=SMA(VAR4,3,1);
VAR61:=crOSS(VAR4,VAR5) AND VAR4<800;
FILTER(VAR61,7);
请老师将两者和二为一。不胜感激涕零

 

VAR2:=(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))*100;
VAR3:=SMA(VAR2,5,1);
VAR4:=SMA(VAR3,3,1);
VAR5:=SMA(VAR4,3,1);
VAR61:=CROSS(VAR4,VAR5) AND VAR4<800;
MID:=MA(CLOSE,20);
LOWER:=MID-2*STD(CLOSE,20);
C<LOWER AND FILTER(VAR61,7);
